Toall whom tney-concerne@ i 5 ABe it known that I, ARTHUR CONNOR, a

plugl whichV maybequiokly and withk little` lin which means` isprovided for locking the which may be quickly openedwith-very lit-V citizen of the United States, and a resident of Chicago, in the county of Cook and State oflllinois, yhaveii'lvented a new and useful Improvement in' vPlugs vfor Icefand`-Hot *Wlater Bags, ofwhich the following is a full, clear, and exactA description.

My' 'nvention relates to" improvementsl in plugs for ice and hot water bags," and 1tV consists in the combinations, jconstructions and yarrangements herein; `,described and.,k

claimed. l

An object Vof inyfinventionis to provide a device of the 'characterd'escribed havinga effort loperatedto seal themouth Aof an ice I riveted or otherwiseiixed to theplate 9.

or hot water bag. e g f Y n n. A further object ofmy invention is to provide a device of the character described,

plug in its sealed condition Aby the pressure exerted from they water withinthebag.

A. further Yobject of Vmy inventiony is-to provide a device'of the character described,

tle physical effort. A further Objectgof my invention is to provide adevice ofthe character described,

which is very durable and which may beY cheaply manufactured.` I v Other objects. and advantagesk will appear in the following specification,rv and thel novel features of the invention will be particularly pointed out inthe appended claims.

My `invention is illustratedV in the ac I companying drawings', forming part of this i. 1--1 of Fig. 2,

applicatiom'in which y n,

Fig. 1 is a sectional-view along the line Fig. 2 is a topplanvview of the device Fig. 3 is a. sectional Vview along the' line` 37-3 Of l, i

Fig. 4 is an end elevation of the plug, andV l Fig. 5 is a partial sectional view showing i `one of the small ducts used in locking the plug'.V Y y' i In carrying out my invention, I makeuse of thek ordinary typeof ice or hot' water Y bag 1 having a relatively large open neck 2. `A plug 3 of hard vulcanized'rubber is closely fitted into the opening of the neck 2 and is provided withan outwardly eX-v Ytending portion; -asshown at 4c for prevent- King Hthe plug3frombeing pulledy out of the ing device.

' The body portion 3 provided withl a Cavity 5' in the upper surface thereof having any arcuate bottom' surface 6, `'as yshown jin Fig; 3.V Thefcavity'fegtends to a point adjacent the lower surface 7 yof the body 3` and elongatedv slot'fS is provided e5" A'through the 'body portion 3 connecting the cavity 5 with the interior of the bag 1.` y

Vmetalk plate 9 is. securely fixed tothe upper!k i* surface of the body 3- and a resilient plug" lOof soft pliant rubber is'hingedly'mounted atone end/thereof uponthe plate 9 by means-r ofainetal plate 11r attached thereto and connected` by a hinge 12.y The hinge 12 is? Means forlocking theplug l10 in a posi-V cavity 5. The spring clip 13 is of spring steel and will give `slightly as the plate 11 engages therewith to permit the plate 11to pass belowfthe clip 13 and be yieldably held p i thereby. i

Means lfor reenforcing the plug 10 and for holding the plug in its normal operative shapev and resilent condition is provided in a bolt 15, which bolt is passed through the plate ll'down through the plug-10 and through an' elongated washer 16 disposed in a depression 17 Onthe under'arcuate surface ofthe plug l0. .The ends of the bolt 15 are Venlarged to prevent the movementof the plate 11 and the washer 116. A second Vbolt A18 is connected to i the washer 16 through the plug 10 andthe plate 11.Y The bolt 18, however, extendsbe' yond the upper surface of the plate 11 `and from* its engagement with -the cavity 5 or forcefully'k pressed into the cavity 5.l Means for preventing theiescape of water fromthe bag 1 `between the contacting walls ofthe rplug 10 and thebody portion 3 and for forcing the plug 10 toward` the clip 13 is` provided in a rib 20 on one wall of the cavity 5vand a shallow groove 21 in the plug 1() and which 'groove is arrangedto registerwith th'e'rib 2() when theplug is closed .and the rib 22 provided ontheibody portion the opposite `end of the cavity 5, there beingV a 'shallow'y groove 23, 'which groove is adapted to registerfwith ytheV rib 22. i

is i tionfto sealthe .cavity 5Vis` provided for in t spring clip 113 riveted at 14 tothe plate `9 and [arranged to overlap the edge of thel f f Means forautomatically lockingthe plug l() against its seatin thecavity isprovidedin the following structure. The plug l has at its outward end a downwardly ci;-

: tending tongue 24. rl`he tongue 2i is tapered inca manner shown in Fig. 4L of tli'edrawiiigi 1A cavity 25 in the end wall of the cavity 5 l ioY 7 ity of transversely extending teeth' 2T.Vv n

is provided to register with and receive the tongue 2-when the plugrlO is properly seated-V in the cavity 5; The outer wall 26 of the cavity '2 5 has formed thereona pluralpair of ducts 28 is proviced in the body portion 3l and serve as a passage for water Vfrom-the bagl lto the under surface of the tongue 24. `This is most Vclearly showninf Fig. 5'. It should be` noted that the ducts 28 are relatively siiiallkin diameter` at a point Y 1 i adjacent the tongue 24 and relatively large at the points adjacent the bottom Z of the L body portion From the vforegoing description of the variousparts of the device, the operation'thereof may be readily understood.V inY filling the .bag,.it is vnecessary first to manually grip V`the knob 19 V'and pull upwardly thereupon.

The plug l0 will be disengaged from itsk seat in the cavity 5 and its engagement with the spring 13. The bag is then filled with hot or ice water. In closing :or sealing the bag, thebody portion Bis held in the position shown in Fig. 3 with the bagproper lying in a horizontal plane. riheY surplus air ispithen worked out through the passage 8 and the plug manually forced to the position .shown in Fig. l by pressure brought to bear on the knob 19. At this time thev clip l13 will be engaged by the plate 11,*tlic tongue 24C will be vsnugly fitted in the cavity 25 and ther ribs 20 and 22 will bear upon the plug l0 vin their respective grooves 2l and 23.

'lhe bag is now ready yfor use. Let us assume that eXtreme pressure is placed upon .the bag l, such asV theweight of a patient .Y thereupon, as might occur if the bag were placed 4under a patients shoulder or the like; The pressure of the water on the in ISide of the bag will tend to pushV the plugVv l0 away fr oin its seat in the cavity 5. However, because ofthe particular' construction Y ofmy plug, pressure will also be exerted up.-

, waterA which wouldpass throughthe ducts' on the under surface of the 'tongue2el by 28 and Contact the Yunder surface. 'This .pressure upon the under surface of 'the tongue 24 `will tend to forcejtlie tongue 124 kinto close engagement with the vteeth "26 on the `wall-'ofthe cavity'25l and the tongue 24 will be held against rnovementin theV cavity. yThespring clip 13 will 'furtlieiz more exert a. downward pressure upon the plate il and materially aid inloclring the the contents .of the bag i upon the under surface of the tongue 2li will be increased proportionally and the plug l0 will therefore remain in its sealed position in the cavity 5 until -it is manually lifted out of engagement with the cavity 5 by means of the knobv 19. in important advantage of the structure heretofore described is that the y body portion 3 is relatively flat and therefore .does not present irregular surfaces which might irritate' the patient from contact` therewith. y
